Game action animations stop, music stops, but game plays normally

[Valcarde]

Yes, it was only happening on the new PC.
I did a full reinstall of windows, after flashing my BIOS on the MB to the most recent release (turns out there had been an update in the last week or so). It was happening anywhere and everywhere, from loading screens having the music drop, to walking around outside, using a striking dummy, tanking in instances, anywhere.

I installed OBS to attempt to capture this after my reinstall and BIOS flash, however, it would appear the BIOS update resolved the issue; it seems the MB was throttling down the processor to 1500mhz or so and causing a bottleneck.

EDIT: And as I say that, it happens again; I was swapping to WAR from FSH in Upper La Noscea to help with a fate, and my emote wouldn't play (though it hit the chat log), music cut out (but other sounds were playing) and when I swapped back to FSH, I remained equipped as a WAR. Back to the drawing board.
